Answer:
365 messages
Step-by-step explanation:
x = # text messages)
16.5 = 10 + .10(x - 300)
6.5 = .10x - 30
36.5 = .10x
x = 365
Setup 2 problems
2x - 7 < 15 and 2x - 7 > -15
2x < 22 2x > -8
x < 11 x > -4
Or you can write it -4 < x < 11
Answer:
#3: 81
Step-by-step explanation:
I haven't done this type of math in a while so I'm unsure about #1 and #2, but #3 is 81.
3^4 = 3 × 3 × 3 × 3
3^4 = 9 × 3 × 3
3^4 = 27 × 3
3^4 = 81
Answer:
40.5
Step-by-step explanation:
Basically use the formula 1//2(base1+base2)*height. So it would be 1/2(4.5+9)*6 which would simplify to 40.5.
1/4 Of 600 Is 150 And 70% Of 300 Is 210. That Means, 70% Of 300 Is Better!
